ICC REINFORCED CONCRETE TEST PAPER 2025 QUESTIONS
WITH SOLUTIONS GUARANTEE A+
✔✔Spiral Reinforcement - ✔✔Lateral reinforcement consisting of an evenly spaced
continuous spiral held firmly in place by vertical spacers. Spiral reinforcement should
have a diameter of at least 3/8 in. (9.5 mm) with a maximum center to center spacing
between spirals of 1/6 of the core diameter, and a clear spacing between spirals not the
exceed 3 in. (76 mm) nor be less than 1 3/8 (35 mm) or 1 1/2 times the size of the
coarse aggregate.
✔✔Compound Column - ✔✔A structural steel column encased on concrete at least 2
1/2 in. (64mm) thick reinforced with wire mesh.
✔✔Composite Column - ✔✔A structural steel column thoroughly encased in concrete
reinforced with both vertical and spiral reinforcement.
✔✔Reinforced Concrete Slab - ✔✔A rigid planar structure of concrete designed to act
together with principal and secondary reinforcement in resisting applied forces.
✔✔One-Way Slab - ✔✔A concrete slab of uniform thickness reinforced in one direction
and cast integrally with parallel supporting beams. One-way slabs are suitable only for
relatively short spans.
✔✔Beam-and-Girder-Slab - ✔✔A one-way slab supported by secondary beams which
in turn are supported by primary beams or girders.
✔✔Ribbed Slab - ✔✔A reinforced concrete slab cast integrally with a series of closely
spaced joists which in turn are supported by a parallel set of beams. Ribbed slabs are
designed as a series of parallel T-beams and economical for medium spans with lights
to medium live loads. Also called joist slab.
✔✔Two-Way Slab - ✔✔A concrete slab of uniform thickness reinforced in two directions
and cast integrally with supporting edge beams or bearing walls on four sides. Two-way
slabs are economical for medium spans with intermediate to heavy loads.
✔✔Continuous Slab - ✔✔A reinforced concrete slab extending as a structural unit over
three or more supports in a given direction. A continuous slab is subject to lower
bending moments than a series of discrete, simply supported slabs.
✔✔Principal Reinforcement - ✔✔Reinforcement designed to absorb the stresses from
applied loads and moments.
✔✔Shrinkage Reinforcement - ✔✔Reinforcement placed perpendicular to the principal
reinforcement in a one-way slab to absorb the stresses resulting from shrinkage or
changes in temperature. Also called temperature reinforcement.
, ✔✔Topping - ✔✔A thin layer of high-quality concrete placed over a concrete base to
form a floor surface.
✔✔Bonding layer - ✔✔A thin layer of mortar spread on a moistened and prepared
existing concrete surface prior to laying a new concrete slab.
✔✔Distribution Rib - ✔✔A rib formed perpendicular to joists of a ribbed slab to distribute
possible load concentrations over a larger area, one required for spans between 20 and
30 ft. (6 and 9 m) and two for spans over 30 ft.
✔✔Joist Band - ✔✔A broad, shallow supporting beam for a ribbed slab that is
economical to form since its depth is the same as that of the joists.
✔✔Pan - ✔✔A reusable metal or fiber glass mold used in forming ribbed slab, available
in standard 20 and 30-inch (508 and 762 mm) widths and a variety of depths.
✔✔Tapered Endform - ✔✔A pan tapered to form thickened joist ends for greater shear
resistance in ribbed slab.
✔✔Panel - ✔✔A portion of a reinforced concrete slab bounded on all sides by the
centerlines of columns, beams or walls.
✔✔Panel Strip - ✔✔A strip running in each direction of a two-way slab, within which
moments per foot are assumed to be constant.
✔✔Middle Strip - ✔✔A panel strip, one-half panel in width and symmetrical about the
panel centerline.
✔✔Column Strip - ✔✔A panel strip occupying the adjacent a quarter panels on both
sides of a column centerline.
✔✔Punching Shear - ✔✔The potentially high-shearing stress developed by the reactive
force a column on a reinforced concrete slab.
✔✔Shear Head - ✔✔The over stressed region of a reinforced concrete slab at a column
support.
✔✔Drop Panel - ✔✔The portion of a flat slab thickened around a column or column
capital to increase the resistance to shear.
✔✔Column Capital - ✔✔The head of a column support for a flat slab enlraged to
increase the plate area in shear.
